A work in progress project to create a scripting framework in Python by using a nodal approach built in PySide2.
Watch demo
My goal for this project is to create a visual scripting API for Python. Alternatively, one could also use it in software that implements PyQt/PySide and generate a scripting framework much like the Blueprint system in Unreal Engine.
Essentially a convenient way to program without writing code, handy for technical artists who have less time to dive into coding mastery.
It is a mix of a case study of more complex components of PySide and the challenge of creating a visual scripting language, which is a noteworthy endeavor by itself since it has always been my dream for a long time after discovering the Blueprint system of UE.
The project uses poetry as the package manager:
poetry install poetry run python -m src.main
Note Currently the project is in a very limited state.
- You can create nodes via the Toolbar, Menu Bar or right click context menu.
- You can connect nodes by left dragging an edge from an output socket.
- You can load, save files.
- You can execute some of the nodes which are part of the execution flow.
- If you use Visual Studio Code, you can use the task
Create sample node - Or you che call the script
create_node.pywhich is located inside the scripts.
In Both cases you will be asked for a node class name and a node name, which can be anything.
Once created, the script will create a new file inside src/nodes/classes with the new node.
The node will start as a blanket template, i.e., no sockets.
The node is subdivided into two sections: The Node class and the Node content. The node content is where you would put the node's logic with its appropriate sockets.
For now, I suggest looking at other nodes inside the nodes/classes folder to see how they work.
Ideally, it should be documented, but I don't think it is appropriate at this stage since much of the code is likely to change.
- Although the core logic is there, the project is not exactly in a working state. I am still trying to figure out most of the nodes with their execution, and there are many bugs and unfinished features.
- I want to give merit to Pavel Křupala for inspiring me to start this project.
